EFFECT OF SOME B10-FERTIUZERS COMPARED WITH CHEMICAL FERTIIZERS ON GROWTH YIELD AND ACTIVE CONSTITUENTS OF CHAMOMILE PLANT Matricaric Chamomile

Abstract

This study was carried out at the Applied Research Center of Medicinal Plant Farm of National Organization for Drug Control and Research (NODCAR) at Kafer El-Gabal Farm, Giza, during the two successive seasons of 2002/2003 to investigate the effect of some chemical (ammonium sulphate, calcium superphosphate and ammonium sulphate + calcium super phosphate) and Bio one as (Azotobacter + Azospirillum, Bacillus and Azotobacter + Azo.'>jJirillum + Bacillus) on

growth, flower yield and chemical compositions of Matticaria chamomile plant. The obtained results were :

1- Chemical and hie-fertilizers increased plant height, fresh and dry weights of plant herb, fresh and dry weights of flower heads/plant or unit area.

2- Chemical and hie-fertilizers treatments also increased essential oil percentage, essential oil yield and of oil improved oil quality.

3- All treatments increased each of nitrogen, phosphorus and potassium percentage in plant herb compared with control plants.

The best results of growth or flower yield, oil percentage and oil quality were obtained with combined treatment of mineral fertilizer and with the bio fertilizer of Azotobacter, Azospirillum and Bacillus.
